    Anybody out there out got a rear 12 bolt with 3.73 gears for pretty cheap I don't have to have it for a while my 10 bolt hasen't gone yet but with my 16 year old mind and 33's with a TBI 350 im afraid it won't last long.

    If you want to stay six lug I suggest you look for a SF 14 bolt, stronger than a 12 bolt and still 6 lug.

    <font color=purple> Yeah, but the problem is finding a 14 bolt SF ........ besides, don't you have to redo the perches if you go with one of those ? Correct me if I'm wrong.

    Yea, they can be difficult but if it's not broken yet that gives you time to look for one [​IMG] and in my Own opinion changing the perches is worth the extra strength ...

    Deals can be found!!!I just bought an full 'Burb with everything in boxes and body off the chassis for $300.All the drivetrain is intacted(350/TH400/208),3/4 ton diffs.EVERYTHING!!!!Now I'm trying to get the monster home.I can't wait to install the diffs!!!I bought my K/5 6 weeks ago( drove it home),and i haven't driven it yet because I keep doing projects on it.But it is ready to roll, it's gonna be a screamer!Did I say that I bought the K/5(78') for $800.So far I have about $1500 in it with the $300 'Burb.I'm glad I did not swap in the 10 bolt 3.73's....but that's a given!!Keep looking....you never know what will turn up!

    I think I will just take my drill and drill 4 more holes in my 10 bolt and put 4 more bolts and have me a 14 bolt rearend.That thing would be unbreakable and cheap lol.

    There are a few different versions of the 14B FF and not all will work for a 6 lug conversion. tried like mad to find one but have come up empty [​IMG]
